Abstract: Various arrangements for establishing a bidirectional satellite communication session are presented. Initialization data may be accessed to tune an antenna to a geosynchronous satellite, wherein the initialization data is stored locally by the access node. The initialization data may be used to point and tune the antenna to the geosynchronous satellite. Ephemeris data may be received from the geosynchronous satellite. The ephemeris data may be indicative of orbital locations of satellites that are part of a non-geosynchronous satellite constellation. The ephemeris data may be used to point and tune the antenna to a satellite of the non-geosynchronous satellite constellation. The bidirectional satellite communication session may then be established with the satellite of the non-geosynchronous satellite constellation.

Abstract: A method of treating a cancerous region in a breast and/or in the head of a patient using a single radiosurgery device by placing the irradiation unit on an axle is disclosed. By pivoting the whole irradiation system, the treatment space can face different directions to accommodate the site of treatment. By continuously or sequentially pivoting the irradiation head unit and assigning different irradiation times to different pivoting angles, not only maximum degrees of expansion of the solid angle can be used for focusing the radiation beams to the target but also different regions of non-target tissues can have different shares of radiation doses based on how critical and radiation tolerant they are.

Abstract: A method and system for gracefully reducing demands for shared decompression resources required to present multiple video streams concurrently such that their streaming video content is simultaneously available for further processing or display. In particular, it relates to the use of presentation time stamps or incoming frames with reference to a time base dock and a threshold to determine if the decompression resources are falling behind in their ability to process incoming frames in real time. If this occurs then frames are dropped, i.e. discarded without being decompressed, with preference given to dropping incremental frames rather than key frames.

Abstract: A fluid metering system for accurately measuring and dosing one or more fluids. The fluid metering system generally includes a closed loop feedback system that monitors the volume of liquid chemical input into a system over a period of time. Based on the measured amount of chemical input into a system over a period of time, the system calculates whether or not an adjustment is required for the next input of chemical. The various embodiments utilize a measuring tube that is filled with a liquid chemical. A pressure sensor measures the pressure of the chemical in the measuring tube when filled and after emptied to calculate the total volume of chemical input into the system.

Abstract: A solenoid valve comprises first, second, and third ports. The solenoid valve further comprises an armature movable between a first position in which fluid flow from the second port to the third port is blocked and fluid flow from the first port to the third port is unblocked and a second position in which fluid flow from the second port to the third port is unblocked and fluid flow from the first port to the third port is blocked. The fluid flow in the second position is blocked until fluid pressure at the first port exceeds fluid pressure at the third port by a predetermined amount to thereby provide check valve functionality. The check valve functionality is integral to the armature. The solenoid valve also comprises an energizeable solenoid that, when energized, moves the armature from the first position to the second position.

Abstract: An apparatus for improving exhaust gas recirculation performance is provided which induces improved exhaust gas recirculation flow during engine operating transients, including transients in which exhaust gas flow conditions are unfavorable. The apparatus includes a fresh air intake passage with a venturi section and an exhaust gas recirculation passage outlet, preferably in the form of a pitot tube, arranged in the fresh air intake passage adjacent to the venturi section such that a pressure-reducing flow in the fresh air is induced as a result of the Coand? effect. Establishing Coand? flow adjacent to the exhaust gas recirculation outlet substantially assists in drawing exhaust gas into the fresh air intake flow in transient operating conditions, including unfavorable exhaust-to-intake pressure difference conditions. The Coand? flow also assists in more rapid and thorough mixing the gases to provide a homogeneous mixture to minimize NOx production during engine operating transients.
